Format number as currency in JTable?

Format number as currency in JTable?

Given a JTable where one of the columns contains a number, how do I display that number as currency? That is, 5 should display as $ 5.00, etc.

Can this be done directly on the JTable after it has been populated with data, or do I need to do this earlier? Thanks.

The Renderers table format shows how numbers and dates can be easily formatted.

There are several ways to approach this. The easiest way is to just populate this column with a custom object that implements currency formatting in its method toString()

.

Another is to use a custom cell renderer. Here's a sample code to set it up. The advantage of this would be that it was "made directly onto the JTable after it was filled with data".
